6 FAQs about [Photovoltaic inverter igbt explosion]

Why is IGBT used in a central inverter?

The IGBT is usually used to the central inverter topology as it can carry high current capacity with several fluctuations (overshoot and undershoot) due to the radiation disturbances because of the clouds cross or sandy windstorm. However, the investigated work can be implemented to other inverter applications which used MOSFET.

What are IGBT based power switching devices?

These inverters dominantly comprise of power semiconductor based switching devices. Insulated Gate Bipolar Transistor (IGBT) based power switching devices are mostly utilized for inverters in GCPS . The IGBTs in inverters are exposed to diverse and rigorous working conditions and therefore, they are susceptible to failure conditions .

Does central inverter failure affect PV power plant availability & Roi?

This paper reviewed several publications which studied the failures of the PV power plant equipment’s and presented that the central inverter failures rate is the highest for the PV power plant equipment’s which affected negatively in both PV power plant availability and ROI.

Why do PV inverters fail?

Some authors discuss inverter failures due to the issues of reactive power control. The PV inverters operate at unity power factor, but as per the new grid requirements, the PV inverters must operate at non unity power factor by absorbing or supplying reactive power to control the grid voltage and frequency.

Which module is most vulnerable in photovoltaic (PV) systems?
